AKA Tournament Arc: The Series
I discovered this "manga" recently and it is truly awesome. Has anyone else been reading this?
Quick rundown for those who aren't: Everyone lives in this massive tower with most (and by most I mean 7 billion people) living on the 1st floor (The first floor being around the size of Earth and an absolute hell hole). If you're chosen, you can attempt to climb the tower, which you do by taking a series of tests, sometimes in a team, sometimes by yourself. If you reach the top of the tower, you get your deepest wish granted.
This is the story of a young lad who fell ass-backwards through this whole scenario. His name is Twenty-Fifth Baam, and unlike everybody else he is pretty much a completely normal person with no superpowers who accidentally finds himself climbing the tower in search of a friend who went to climb it before him. In doing so he befriends a massive alligator-man named Rak Wreckraiser and a cunning prankster named Koon whose trying his hardest to exploit all the loopholes and **** up the status quo with the help of an infinite briefcase.
Did I mention it was awesome? Because I feel I cannot stress that enough.
The bolded interests me.
The First floor is only ever shown in other characters' backstory, but basically the tower is ruled by this guy named Zahard who was the first to climb the tower who was also the first "irregular", someone who is not chosen to enter the Tower but enters by force. Historically speaking, the four Irregulars there's been in the past have been so powerful that they've brought the Tower to it's knees so that now Irregulars are universally feared. Unfortunately, Baam's an Irregular too.
And Rak's a badass.
